A Probing for SCSI Devices

Follow these instructions to probe for SCSI devices in your SPARCcenter 2000 or SPARCserver 1000 system:

1. Halt the operating system.

Refer to your system installation manual for the appropriate commands.

2. Wait for the system-halted message and boot monitor prompt.

• If you see the ok prompt at the end of the system messages, go to Step 3.

• If you see the following screen at the end of the system messages:

------------------------------------------------------

Type b (boot), c (continue), or n (new command mode)

------------------------------------------------------

>

type the following command:

--------

> n 

--------

This will bring you to the ok prompt.

3. Locate the system board (in the card cage) to which the device is connected.

4. Determine the slot in which the system board is installed, and write that number here: ____

5. Determine which SBus slot in the system board holds the card for the device and write that number here: ____

6. Enter the appropriate command to probe your system for SCSI devices.

This command depends on how you want to probe for SCSI devices and the SCSI port to which you have connected the device.

• If you want to probe for SCSI devices off of every SCSI port on your system, enter the following boldfaced command:

-----------------------

ok probe-scsi-all 

-----------------------

and find the section that gives information on the SCSI port for your device.

• If you want to probe for SCSI devices off of a specific SCSI port on your system, enter the following boldfaced command, where A is the board slot number (given in Step 4) and B is the SBus slot number within the board (given in Step 5):

-------------------------------------------------------------------

ok probe-scsi-all /io-unit@f,eA200000/sbi@0,0/dma@B,81000 

-------------------------------------------------------------------

For example, if the tray is connected to a card installed in SBus slot 1 in a board, and the board is installed in board slot 2 in the SPARCserver 1000 card cage, you would enter the following boldfaced command:

-------------------------------------------------------------------

ok probe-scsi-all /io-unit@f,e2200000/sbi@0,0/dma@1,81000 

-------------------------------------------------------------------

7. Verify that all devices connected to the SBus slot are listed.

You should see a list of drives similar to the following:

----------------------------------

Target 0
	Unit 0 Disk <drive brand name'>
Target 1
	Unit 0 Disk <drive brand name'>
Target 2
	Unit 0 Disk <drive brand name'>
Target 3
	Unit 0 Disk <drive brand name'>

----------------------------------

The Target # lines will tell you the SCSI addresses of the devices you have connected to your system. If you see the SCSI addresses for the devices listed, then the installation was successful. If you don't see the SCSI addresses for the devices listed, then verify that the cables are installed correctly.

8. Enter the following boldfaced command to reboot your system:

----------------

ok boot -r 

----------------

Your screen will go blank for several seconds after you enter this command, and then the system will reboot.
